LAST LATHE.

Application filed May 7,

An object of my invention is to provide a simple and efficient last lathe structure} Another object of my invention is to pro vide a direct drive of the cutter head.

incident to the disposition of the axis of the cutter head in a horizontal plane willbe obviated by providing means for moi'inting' the cutter head with its axis iiiia vertical plane. p a

These and other objects are attained by the means described herein andv disclosed in the accompanying drawings, in which:

7 Fig. 1 is' a perspective view ofa cutter head and driving mechanism therefor 6111-. bodying my 1I1VeI1t1011, together with a frag ment of the Ways of a lathe bed upon which same are mounted.

Fig. 2 is an enlarged perspective view of a cutter head frame, parts being broken away, and embodying my invention. 7

Fig. 3 is a perspective view of a cutter head plate forming a d-etail .of my invention.

In the position to engage a block fl'OlnWVhlCli the last 6 is be ng turned. 7 'llns'Carnage is remounting of the cutter head 5, and I the means for rotatably actuating same, The carriage4 carries a depending bracket 11 upon the lower end of which a motor 12 is mounted for vertical adjustment.

bracket 15'is mounted in a way 16 formed in the upper face ofthe carriage for'adjustment transversely of the cari'iage,iand carries a journal bearing 160 supporting a suitable bearing block 17 for the upper end 7 Although I have shown; the cutter as mounted directly upontheiipperend of usual last lathe construction a carriage 4 is' prov ded for carrying the cut- .ter head 5 in a suitable manner and iii ap The motor shaft 13 is disposed in a vertical.

cutter head fram'e. 18.-. Any suitable mountu 7 vjing means may be provided for example by; Another ob ect of my invention is to provide a dev ce wherein the d sadvantages providing a shank 19:11:}3011 thecutter head frame, the shank having'a threaded bore 20 for the reception of the complementary threaded upper end of the motor shaft 13.

The cutter head frame comprises a plurality of radially extending wings Ql'upon each of the frame, for example bolts may bepassed through the apertures 24 provided in discs The operation of the device isobvious.

Any suitable means foreffecting highspeed of the motor maybe employed. I I r the motor shaft; my invention isff not restricted to this direct mounting although it vis preferable to'have adirect drive.

'What I claim is In a last lathe the coiiibinationfwith a lathe bed, of a carriage reciprocally mounted on the lathe bed and having a bore there-4 through, a depending bracket mounted on the bottom of the carriage, a vertical motor carried by the depending,braol et and having an elongated vertical armature shaft exhead and lodging in suitable bores 25 in the .1 3 cutter head frame.

.tending upwardly throughthe bore'in'the carriage, bearing arranged'work. 1 j 1 In testimony whereof, I have hereunto bracket adjustably mounted upon the upperside of the carr riage for receiving the projecting end of the armature shaft, and arotary cutter mounted on the free endofthe armature shaft adapted to engage the side of the horizontally 1" subscribed my name this 3rd dayf'of 'May,
